+# Sgvizler
+
+Sgvizler is a javascript wrapper for easy visualisation of SPARQL result sets. 
+
+See http://mgskjaeveland.github.io/sgvizler/ for how to set up, use, and extend Sgvizler, including documentation, downloads, and examples.
+
+Add visualisations directly into your webpages like this:
+```html
+<div id="example"
+     data-sgvizler-endpoint="http://sws.ifi.uio.no/sparql/npd"
+     data-sgvizler-query="SELECT ?class (count(?instance) AS ?noOfInstances)
+                          WHERE{ ?instance a ?class }
+                          GROUP BY ?class
+                          ORDER BY ?class"
+     data-sgvizler-chart="google.visualization.PieChart"
+     style="width:800px; height:400px;"></div>
+```
+to get charts like this:

+
+	ii) "npm install -g npm"
+
+	iii) Yuidocjs : "npm -g install yuidocjs."
+
+	iv) "npm install uglify-js -g"
+
+2. "Compile" with makefile :
+
+	i) Type : "yuidoc." at the source of the tree.
+	This will generate a ./out directory
+
+	ii) Being in ./sgvizler, type "make sgvizler.js" 
+	This will create all necessary files thanks to Makefile
+	
+	iii) Finally, type "uglifyjs sgvizler.js -o sgvizler.min.js"
